3 PROGRAMA DE VIGILANCIA AMBIENTAL

Introduction

• Normally Incoming Calls to the phone will be on the first available line of SIP1 or SIP2.

• The associated LED of the line-key (if assigned) will glow and the phone will ring.

• If there are multiple lines ringing, you can select the line, which you would like to answer.

• At the end of the call, hang up the handset to disconnect the call. • Maximum calls the IP phone user can receive simultaneously is

equal to the number of CAs programmed. This means, if number of CAs programmed are ‘4’, user can receive maximum of four calls simultaneously.

• For Example, if number of CAs programmed are 4, first incoming call will occupy the CA1.

• Second incoming (waiting) call will occupy the CA2. If user answers the call on CA2, the current call will be put on hold and user will come in speech on CA2.

• Third incoming (waiting) call will occupy the CA3. If user answers the call on CA3, the current call (on CA2) will be put on hold and user will come in speech on CA3.

• Fourth incoming (waiting) call will occupy the CA4. If user answers the call on CA4, the current call will be put on hold and user will come in speech on CA4. Now, user has four held calls and user can toggle between the calls as per the requirement. All further IC calls will be rejected.

Ways of answering a Call:

• Using the Handset • Using the Headset

• Using the Speaker, If Auto Answer enabled • Pressing the Call Appearance Key

Using the Handset:

• This is a most common method like analog telephones. You can just pick up the handset before expiry of rings and start talking to the caller.

Using the Headset:

• In this method, you can press the Headset key and start talking.

If Auto-Answer enabled:

• This is a special feature, enabled on the Web page programming or by the programming of key. After some time, call will be answered automatically by the Phone and you will get audio of calling party through head phone.

Using the Speaker:

• Like normal analog phone, you can press the speaker key and start talking.

Pressing the Call Appearance key:

• When Incoming call comes and you are busy with an outgoing call, the corresponding Call Appearance Key LED is glowing.

• Press the key and start talking.

• Refer chapter ‘Call Appearances’ for more information.

How it works?

How user gets information of the IC call ?

• When Phone is in Idle condition, ringing indication is available on the Phone.

• When LED of the Call Appearance (CA) key on which the call has arrived, is glowing/blinking. Refer topic ‘Call Appearances’ for more details.

• Getting the display of the Calling Party’s Number/Name (CLI) on the LCD.

When user can answer the incoming call?

• When phone is Idle.

• While user is talking to another user.

• When one user is held during a speech to the called party. • When more than one user is held.

Important Points:

• If the user is in speech with a remote user and if another call arrives which can be treated as waiting call, Auto Answer will not be effective. The user will get Call Waiting indication.

• Auto Answer is effective only if there is no held call and the user is idle.

• If the user is trying to configure some feature. That means, the phone is under ‘Configuration’, then the Incoming call cannot be answered. But if still the user wants to answer the call, he will have to stop configuring the Phone, exit the SE Mode and should go OFF-Hook.

• While using headset, if user unplug the headset, call is not dis- connected. User can again plug the headset and start conversation. • Since, the Phone has two DSP channels and remote held call uses

the DSP channel, maximum of two calls can be received if the same calls are held by remote user after answering the call. Refer chapter ‘Call Hold’ for ‘Remote Held’.

• However, if there is an incoming/ waiting call when user has two calls held by remote users, user will still get incoming/waiting call notification on relevant CA. But, it will not be possible to retrieve the waiting call since no resources are available to entertain the waiting call. But to receive the waiting call, user will have to release one of the calls held by remote user.

• It is possible to answer the waiting call when user has Active Conference. Maximum two calls can be answered when the user has active conference.

• When user has active conference which will occupy two CAs and there is a waiting/ incoming call, user can answer the waiting call and the two calls involved in conference will be put on ‘hold’. User will come in speech with the waiting caller.
